Static overlay plus dynamic content switching

You can combine the static overlays with the dynamic content switching feature. You can use dynamic content switching to continually add and modify inputs in an event that is running. As you add inputs, you can insert static or motion overlays, as desired. For information about dynamic content switching, see Dynamic input switching.

Scheduling inputs and overlays

The scheduling of the inputs and the overlays is completely decoupled.

A given input X might be added several times to the dynamic playlist, for example, so that it plays at 2:00 p.m. and then plays again at 3:10 p.m.

If you want an overlay to appear the first time that input X plays, you might set its start time for 2:10 p.m. The next time that input X plays, there is no logic to play the same overlay again because 2:10 p.m. has passed. Therefore, if you want the overlay to appear again on input X, you must send a Modify Overlay call again.

Behavior with different insertion options for static overlays

Following are points to remember when using static overlay with dynamic content switching:

Playlist input plus overlay at the input stage

You specify the overlay in the input section of the event. Therefore, whenever you include this input in the playlist, the overlay will be included. If you want to the image the first time the input appears in the playlist but you don't want to include it the next time the input appears, you must unless enter an action to remove it.

  • If you want to include the overlay in a given repetition of the input, you might need to change the start time of the overlay. See the information about the Start Time in the table under Step B: Initial setup.

  • If you do not want to include the overlay in a given repetition of that input, you must use the REST interface to enter a Modify Static Overlay command and delete the overlay. See Static graphic overlay commands.

Playlist input plus overlay at the global processing stage

The scheduling of the inputs and the overlays is completely decoupled.

A given input X might be added several times to the dynamic playlist, for example, so that it plays at 2:00 p.m. and then plays again at 3:10 p.m.

If you want an overlay to appear the first time that input X plays, you might set its start time for 2:10 p.m. The next time that input X plays, there is no logic to play the same overlay again because 2:10 p.m. has passed.

Therefore, if you want the overlay to appear again on input X, you must enter the Modify Static Overlay command again.

The same comments as for global processing stage apply.
